When it comes to installing home built packages, I typically do one of these:
xbps-install -R /path/to/binpkgs foo

Is there a way to simply install a package without a repository?  I didn't notice anything in the man page.

To clarify:
In Archlinux, if I remember correctly, "pacman -u /path/to/package" Will install the package without the need for repo data.
